This section exists because the conversation online is dominated by sellers. It does the opposite: it describes what published research and New Zealand law actually say. It does not recommend anything, does not tell you where to buy anything, and is not a substitute for a doctor.
What sits in this section is the regulatory scaffolding behind the rest of the site: which law applies to a substance, who decides, and what that means for the way a product may be talked about. It is descriptive throughout. The aim is to let you place a claim in the right category, not to tell you what to do about it.
The current page is how peptides are regulated in New Zealand, which sets out the legislation involved and the categories a substance can fall into. For the consumer-facing counterpart, covering what a product may say on its label once it is on sale, see the supplement labelling rules.
